Purpose: Liver metastasis is a common phenomenon in breast cancer patients. Hepatic lesions detected in breast cancer patients may be easily misdiagnosed as metastatic sites, rather than being treated as primary foci. This descriptive study aims to investigate the clinicopathological characteristics of second primary hepatocellular carcinoma in breast cancer patients and to infer in which circumstances liver biopsy is needed. Methods: Eighty-one consecutive breast cancer patients with hepatic lesions admitted to our department were retrospectively studied and analyzed from January 2009 to March 2014 according to Warren and Gates’ criteria for second primary cancers. Results: Second primary hepatocellular carcinoma was observed in sixteen of seventy eight patients with breast cancer. There was a significant difference in HBV status between the second HCC group and liver metastases group (P<0.0001). There was no significant difference in age (P = 0.2254) and family history (P = 0.1160) between second primary HCC and metastases group. Two of these patients had synchronous second primary hepatocellular carcinoma and the remaining fourteen patients had metachronous second primary HCC. All sixteen patients were infected with hepatitis, including hepatitis virus B and C, or resolved HBV infection. Conclusions: Breast cancer patients with either HBV infection or resolved HBV infection, regardless of an elevated AFP level, may receive liver biopsy to avoid unnecessary and inappropriate treatments for metastasis. Awareness of second primary HCC in breast cancer patients needs to be emphasized. [ABSTRACT FROM AUTHOR]

Background: Hepatocellular carcinoma (HCC) can be diagnosed by noninvasive approaches with serum α-fetoprotein (AFP) levels >200 ng/ml and/or a radiological imaging study of tumor mass >2 cm in patients with chronic liver disease. Percutaneous fine needle aspiration (FNA) under ultrasound (US) guidance has a diagnostic specificity of 95% and is superior to radiological imaging studies. Aim: The aim of this study is to elucidate the effectiveness and complications of fine needle aspiration in a Chinese population with primary liver cancer and AFP levels ≤200 ng/ml. Materials and Methods: A retrospective study was conducted over a period of 28 years. This selection period included patients with a suspected diagnosis of primary liver cancer whose AFP levels were ≤200 ng/ml and who underwent US-FNA. This data was then analyzed with cytomorphological features correlating with medical history, radiological imaging, AFP, and follow-up information. Results: Of the 1,929 cases with AFP ≤200 mg/ml, 1,756 underwent FNA. Of these, 1,590 cases were determined malignant and the remaining 166 were determined benign. Further, 1,478 malignant cases were diagnosed by FNA alone, and of these, 1,138 were diagnosed as PLC. The sensitivity, specificity, positive predictive value, negative predictive value, and overall accuracy of the diagnoses were 92.96%, 100%, 100%, 59.71%, and 93.62% respectively. There was no significant difference in the sensitivity, specificity, PPV and NPV between the subgroups with tumor size<2 cm and ≥2 cm. Major complications included implantation metastasis and hemorrhage. Conclusion: Patients with PLC, especially those who present with an AFP ≤200 ng/ml, should undergo FNA. If negative results are obtained by FNA, it still could be HCC and repeated FNA procedure may be needed if highly suspicious of HCC on imaging study. The superiority of FNA in overall accuracy may outweigh its potential complications, such like hemorrhage and implantation metastasis. [ABSTRACT FROM AUTHOR]
